Is it the original battery? Is it a sealed battery, or are there removable caps? If there are removable caps, the you might consider checking the fluid level inside.
Some batteries get old and funky. They will develop a "slow short" internally when the crud builds up between the plates.

Battery slowly drains, taking about 3 days. Measured current between disconnected neg cable and neg bat post while pulling each fuse; current keeps flowing. Any a clue or suggestion ?? ____________________________________________________
Check if drain is alternator:
1.) Disconnect Neg bat cable. 2.) Disconnect fat charging wire from rear alternator terminal. 3.) Measure current between disconnected neg cable and neg bat post. Should be no current if alternator is good.Good luck,

How much current? You must wait for a minute or two for the current to stabilize to get a good reading.
Is the battery initally fully charged? If the battery has caps use a hydrometer to measure it and verify all cells are good. Otherwise measure the voltage with a good voltmeter.

Modern cars always have a small drain on the battery to keep the computer and radio memory alive. The problem could be the battery itself. If it is the original battery, get it checked out.

Would be helpful to mention how much current was draining?? To check the battery just remove the negative cable and see if it dies in three days.

I'd disconnect, and electricly isolate [ a rubber furniture tip works great ] the Alternator wiring. My guess is the alternator has a bad diode, and is sucking power. ** This is only a guess **
